out of sheet metal and provided with'a' finger. piece or key ll). Thelever is formed with an angular projection providing a member or plate41 which is substantially parallel with the body of the lever. The

lever is mounted .on a rod L2 which is fitted in openings in the endwalls 43, ll of the lower casing member. The rod passes through thespacing plate 4:1 as well as through the main portion of the lever. Inthis manner the lever has a double bearing on the rod which prevents itfrom wabbling even though it is made of relatively thin metal. The lever39 is in the form of a bell crank having a short arm 45 which has arotative and slidable engagement with a lever 46 fulcrumed on a rod l7which latter is mounted in the casing member 25 below rod 42. The leverto is also preferably formed with an angular projection 4:8 similar tothe angular projection4l of the lever 39 and serving the same purpose.The lever 46 extends around and above the lever 39 and terminatesin arounded end H) which projects through a slot 50 in the coin ejectingslide-3S. The engagement between the short arm of lever 46 is shorterthan the thereof. The rounded end of the short arm 45 0f themanipulating lever 39 can slide as well as rotate between the lugs 51,'this being necessary in view of the diiferen'ce in radius between theengaging arms.

The coin ejecting slide 3S is formed with down turned flanges 52 whichlie in'slots formed in the base plate 32. The base plate is also formedwith a slot 54 between slots 53 through whichthe end of lever {LG-ex-The lever 46 is formed with a projection 55 connected to a helicalspring 56. The other end of the spring is anchored to a rod 57 which isbound against a rib 5S 7 on the under side of the base plate by means ofcotter pins 59.

. The several units constructed as above described are arranged side byside with the spacing projection of each lever bearing against the bodyportion of the adjacent lever. The end levers are preferablyheld inproper position by spacingsleeves 60, 61.

'In order that twenty cents in change be ejected by a single operation Ihaveprovided the machine with two ten;cent coin pockets 34 3t". Thecoinejecting slide 38, forming a part of a coin ejecting unit, the key 40 ofwhich is marked 10,- is moved, when key 40 is depressed independently ofthe mechanism that ejects coins from the other ten cent pocket 31".- The.38 ejects a coin'from pocket 34?, andat the same time slide 3S is movedto eject a coin from the pocket 34.

The manipulating levers 39 extend through slots 64 in the front plate26. 3 The length of these slots is such that the levers 39 cannot bedepressed far enough to throw the corresponding slide engaging leversinto such position that the latter will not be automatically returned bysprings 56 to their normal positions when the pressure ofthe fingers istaken from the keys.

The coins ejected from the coin pockets are pushedoverthe rear marginaledge of base plate 32 and fall into an inclined receiving chute 65. Thischute is made of sheet metal. preferably, and is'reinovably arrangedwithin thelower casing member 25 with its delivery end communicatingwith an opening (36 in the end wall ie of the casing. In fact, the chuterequires no attachment to the casing. It has enough spring to hold it inthe proper position; To the outside of the casing is attached a coindelivery chute 6 7 which is preferably formed with a bend toward thesideof themachine opposite to the side on which the keys are arranged.The end wall 44 of the casing is formed with slots 68 and the chute withhooks 69 which enter the slots.' The engagement is preferably made morefirm-bya screw 70 which extends through a .lug:71 on the chute and intothe end wall 44:. The receiving chute 65 is preferably formed with a lip72 which overlaps the'delivery chute a trifle. The delivery chute ispreferably provided with a cross piece 73 which stands far e'nough'abovethe bottom of the chute so that it intercepts any rolling coin andcauses the same" to drop on its side andin that the chute. V V

The constructionof the ejectingmechanism is such that the coin isejectedby'a manner slide the rest of the way through.

sharp, quick movementof the ejecting slide.

If the machine be properly operated the coins will be ejected-withoutfail. By a tion preventing the slide when actuated again from reachingthe partially ejected coin. In order to straighten the stack the uppercasing member is formed at the pockets with a plurality of notches 74.and the keys 38 are similarly formed on their inner ends war notches 75. This permits a pencil or other thin instrument to be inserted underthe forward edge of the stack so as to raise it sufliciently to allowthe slide to be brought against the lowermost coin or partially ejectedcoin.

In Fig.8 I have shown a machine, in all other respects like the machinejust described, which is provided with a discharge chute 67 intendedparticularly for deliven ing change to pay envelops, or the like. Thechute is shown as formed with hooks 69 adapted to engage the end of thecasing of the machine through the slots 68, and with a screw 7 O forbinding it to the casing. The intention is to have the machine furnishedwith two chutes of thesort above described either one of which can beusedas required.

In Fig. 9 I have shown the same machine with certain parts interchangedso that the coins will be delivered to the side of the ma chine at whichthe keys are located so that the change may be handled by the operator.This is the usual way in which the change ejected by change makingmachines is handled and while I consider that the immediate delivery ofthe change to the customer, or into the pay envelop as provided by theconstructions previously described, Wlll be orconsiderable advantage, itmay happen that under some circumstances it will bemore desirable forthe person who operates the machine to collect the coins ejected by themachineand give them to the customer or make such other disposition'ofthe same. as the circumstance calls for. In order to modify the machinein such manner that the ejected coins can be conveniently handled by theperson who operates the machine, the front plate 26 of the machine aspreviously described is removed, together with the receiving chute 65,and for the latter a chute 76 (Fig. 11) is substituted. The chute 7 6 isprovided with a slotted lug 77 adapted for engagement with the screw 29which holds together the rear edges of the upper and lower casingmembers 27, 26. At the forward end of the chute are slotted brackets 7 8which hook over the ends of the rod l7 on which the slide engaginglevers 46 are fulcrumed. A front plate 79 is substituted for the frontplate 26. The coins ejected from the stacks fall into the chute 76 andare delivered to the front side of the machine, that is, to the side atwhich the operating keys are located.

I have shown in connection with the machine of Fig. 9 a slightmodification in the construction of the coin ejecting slides which,however, could be used as well in connection with. the machinespreviously de-' scribed. The slide 38 (Fig. 10) has attached to theinner end thereof a bar 80 formed at its extremity with an upstandingleg 81. The bar projects from the slide a distance equal, substantially,to the diameter of the coins of the stack operated upon. The bar movesin the slot 54.- of the base plate formed for the accommodation of theend of the slide engaging lever a6. It lies, nor mally, directly underthe stack of coins. If the manipulated lever 39 is given its full strokeso that the coin operated upon is completely freed from the stack ofcoins above it, the coin will readily fall from the bar 80 into thereceiving chute. On the other hand, if the manipulated lever is notdepressed sufficiently the lug 81 on the bar 80 engages the coin andreturns the same to its normal position under the stack when theoperating levers are returned to their positions of rest by the spring56. By this expedient it is impossible, if a coin is partially ejected,through careless operation, for the coins above it to take an obliqueposition blocking the further operation of the ejecting mechanism.

Resume 07' operation. With the coin pockets filled with coins of theproper denomination, change is made by depressing the manipulated leverscorresponding to the different coin stacks. The throw of the manipulatedlevers is relatively short. The movement of the ejecting slides 38 is,nevertheless, very rapid because of the compound lever arrangements bywhich the slides are operated. The engagements between the le vers 39and the corresponding slide engag ing lev rs i6, and between the latterand the slides, are very free so that the apparatus responds to a lighttouch and the possibility of the parts sticking or clogging iseliminated. The coins are ejected directly into the receiving chute. Theaction is, therefore, simple and positive. There is no danger if themachine is properly operated that the proper coin will not be ejected atevery depression of the key. The machine can be run at a high rate ofspeed which is particularly important perhaps when it is used forplacing change in pay roll envelops. lWhen the machine is used in thisconnection it is preferably provided with the delivery chute 67 (Fig.8). If the ma chine is to be used for delivering change directly to acustomer. in a store or restaurant for example, the chute 67 is removedby loosening screw 78 and uuhooking the chute from slots 68 and thechute 67 is put in its place. This chute delivers the coin toward theside of the machine away from the operator, that is, the side toward thecustomer, so that the operator does not have to handle the coins at all.

If through careless operation a coin should not be fully; ejected, withthe result that thecoins in the stack above take an oblique positionblocking the further opera tion of the ejecting apparatus, this may beremedied by placing a pencil through the notch 7% in the casing and thecorresponding notch 75 in the end of the slide and raising theforward'cdge oi the stack su'fliciently to allow the slide to pass andcome into contact with the partially ejected coin. If the slides areconstructed as shown in Fig. 10, the tilting of the stack cannot occurunder such circumstances, but the provision of the slides with theprojections 80 makes the ejecting action a trifle slower so that, wherethe highest rate of operation is desired, I prefer not to employ thisfeature. When it is desired to have the operator handle the change theinner or receiving chute 66 is removed, together with the'front plate26', and a chute 7 6 (Fig. 9) which deliversthe coins to the front ofthe machine, under the front plate 79, is put in place of theotherchute.

While I have described my invention in certain preferred embodiments, itwill b understood that further modifications might be made withoutdeparture from the principles of the invention. Therefore I do not Wishto be understood as limiting the invention to the particulars describedand shown except so far as certain of the claims are specific thereon.
